    • An air management valve in the exhaust emission control system for the engine of an automotive vehicle is operative to selectively control secondary air flow to the exhaust manifold next adjacent to the exhaust ports of the engine, to the center of a dual bed catalytic converter and to the atmosphere. The air management valve, adapted to be connected to an engine driven air pump, includes three air pressure operated valves, that is, a port air control valve controlling air flow to the exhaust ports, a proportional air control valve controlling divert air flow to the atmosphere and a pressure relief valve for the pressure relief divert air flow to the atmosphere, a flow control orifice controlling air flow to the converter, a port air control and a solenoid valve arranged to control pressure on one side of the port air control valve, a proportion air control solenoid valve arranged so as to control the flow of exhaust gases to one side of the proportional air control valve whereby to effect operation of this valve as a proportional regulator so as to maintain a constant pressure ratio between air pump pressure and exhaust pressure at the center of the converter.
